CNC Lathe Service

CNC lathe is one of the widely used CNC machine tools. It is mainly used for shaft parts or disc parts inside and outside cylindrical surface, arbitrary cone angle of the conical surface, inside and outside the inside and outside surface and complex rotary cylinder cone thread cutting, and can carry out cutting, drilling, reaming, boring and etc..

Reasonable selection of cutting parameters: for high efficiency metal cutting processing, the machining material, cutting tools, cutting conditions are the three major factors. These determine the processing time, tool life and machining quality. The economical and effective machining method is the reasonable choice of cutting conditions. Three factors of cutting condition: cutting speed, feed rate and cutting depth directly cause tool damage. With the increase of cutting speed, the tool nose temperature will rise, and will produce mechanical, chemical, thermal wear. The cutting speed is increased by 20%, and the tool life is reduced by 1/2. The relationship between the feed condition and the wear behind the tool is in a very small range. But the feed is large, the cutting temperature rises, and the back wear is great. It has less influence on cutting tools than cutting speed.

Although cutting depth has no influence on cutting tool speed and feed rate, it is also affected by cutting material hardening layer when cutting in small cutting depth. Users should choose the cutting speed according to the machined material, hardness, cutting state, material type, feed rate, cutting depth and so on. The most suitable processing conditions are chosen on the basis of these factors. Regular and steady wear is the ideal condition for life. However, in actual operation, the choice of tool life is related to tool wear, machined dimension change, surface quality, cutting noise, heat treatment and so on. In the determination of processing conditions, it is necessary to study according to the actual situation. For refractory materials such as stainless steel and heat resistant alloys, coolants can be used or rigid edges are selected.

Product Feature And Application

1) workpiece with three jaw self centering chuck with coarse or fine car car, if the workpiece diameter less than 30 mm, the overhang length should be less than 5 times the diameter, if the workpiece diameter greater than 30 mm, the overhang length should be less than 3 times the diameter.2) chuck, disk with four claws, iron (bending) and clamping on irregular workpiece, must add weight.3) in the machining of shaft workpiece between the centers, the center axis of the tailstock should be adjusted to coincide with the axis of the lathe before turning.

4) the following tool holder or center frame shall be used when machining slender shafts between two centers. In the process of processing, attention should be paid to the adjustment of the top tightening force, the dead center and the center frame should pay attention to lubrication.

Product Details

1) in order to ensure the rigidity of turning, the diameter of the larger part and the smaller part of the rear diameter should be generally used to turn the step shaft.2) the slot should be carried out before the finishing of the workpiece in order to prevent the deformation of the workpiece.3) when turning the shaft with fine thread, the screw thread should be finished after the thread is machined.4) the surface of the workpiece should be flat before drilling. Central holes should be used first if necessary.5) when drilling a deep hole, the drill hole is usually drilled first.6 ) turning Phi Phi 20) mm hole, the knife rod diameter should be processed aperture of 0.6 - 0.7 times; processing diameter 20 mm diameter larger than the hole, should generally be used knife rod clamping cutter head.
